Okay, so we might be chasing the flying unicorn of modern technology here -- and, no, we're not talking about the white iPhone 4 -- but as you've probably noticed, our hunger for a quantum computer is basically insatiable. Lucky for us, some folks who actually know something about producing qubits are similarly persistent -- a team of researchers recently presented a scalable quantum chip at a meeting of the American Physical Society in good old Texas. The 6 x 6-cm processor sports four qubits, the basic units of quantum computing, and its creators say it has the potential to be scaled up to support 10 of the things within the year. So what does that mean for our quest for the ultimate super computer? Well, it means we're closer than we used to be... and the dream lives on.
